Plasma-assisted surface treatment for low-temperature anneal

发布时间：2024-05-07 02:32

　　In this study, a low-temperature annealed ohmic contact process was proposed on Al Ga N/Ga N heterostructure field effect transistors(HFETs) with the assistance of inductively coupled plasma(ICP) surface treatment. The effect of ICP treatment process on the 2DEG channel as well as the formation mechanism of the low annealing temperature ohmic contact was investigated. An appropriate residual Al Ga N thickness and a plasma-induced damage are considered to contribute to the low-temperature anneale...
